این پژوهش به منظور بررسی تغییرات ترکیب شیمیایی و ارزش غذایی سیلاژ قصیل جو با افزودن درصد های مختلف اوره به روش in vitro و in situ انجام شد. بدین منظور علوفه قصیل جو در مرحله نیمه خمیری دانه ها در اردیبهشت ماه برداشت و جهت سیلو نمودن به قطعات 4 - 2 سانتی متری خرد گردید. سپس با چهار سطح اوره (0، 2، 4 و 6 درصد ماده خشک) مخلوط و در سطل های پلاستیکی 2 کیلوگرمی سیلو شدند. سیلو ها پس از 2 ماه باز شدند...
The uncharacterized α/β-hydrolase protein OLEI01171 from the psychrophilic marine bacterium Oleispira antarctica belongs to the PF00756 family of putative esterases, which also includes human esterase D. In the present paper we show that purified recombinant OLEI01171 exhibits high esterase activity against the model esterase substrate α-naphthyl acetate at 5-30°C with maximal activity at 15-20...
The free-living spirochete Spirochaeta aurantia was nearly as susceptible to diacetyl chloramphenicol, the product of chloramphenicol acetyltransferase, as it was to chloramphenicol itself. This unexpected susceptibility to diacetyl chloramphenicol was wholly or partly the consequence of intrinsic carboxylesterase activity, as indicated by high-performance liquid chromatography, thin-layer chro...
Analysis of tissue lesions of the major reactional states of leprosy was undertaken to study the immune mechanisms underlying regulation of cell-mediated immunity and delayed-type hypersensitivity (DTH) in man. In situ hybridization hybridization of reversal reaction biopsy specimens for INF-gamma mRNA expression revealed a 10-fold increase in specific mRNA-containing cells over that observed i...
Received: 21 April, 2009 Accepted: 8 July, 2009 Abstract Background & Aims: Dimethoate as an organophosphorus compound is commonly used for crop production which is neurotoxic in human. Pseudomonas family harbor organophosphate degrading plasmids have been known as tools for cleaning environmental pollutions. Materials & Methods: Pseudomonas Putida was isolated from contaminated soil b...
toury (1978:200) believes that translation is a kind of activity which inevitably involves at least two languages and two cultural traditions. being polite while asking for something takes place differently in different cultures and languages, therefore various strategies may be applied for making requests and also translation of them in order not to disturb or threaten the face or better to sa...
As long ago as 1905, Warburg (1) employed the amino acid esterase activity of tissues to prepare the optical isomers of amino acids. Since that time, other than for the studies of esterase activity of the proteases, there have been only scattered reports of the amino acid esterase activity of tissue extracts. In fact, Smith and coworkers (24) have emphasized that their preparations of “leucine ...
Purified human milk lipoamidase was digested with endoproteinase Lys-C and the digested peptides were subjected to gasphase microsequence analysis. The sequencing of three isolated peptides of human milk lipoamidase revealed the identity of this protein with human milk bile salt-stimulated lipase (pancreatic cholesterol esterase). The identity of the cholesterol esterase with lipoamidase was co...
Field collected An. stephensi larvae were colonized in the laboratory for 15 generations and acclimatized. An isofemale line was raised from this colony and the larvae were subjected to continuous deltamethrin selection pressure. LC50 and LC90 values were calculated at every generation. The values indicated that at the end of seventh generation the larvae have developed 87 fold tolerance in ter...
چکیده این پژوهش به منظور بررسی تغییرات ترکیبات شیمیایی و ارزش غذایی سیلوی علوفه سورگوم با افزودن آنزیم روابیو، اوره و ترکیب این دو به روش in vitro و in situ انجام شد. بدین منظور علوفه سورگوم در مرحله شیری بودن دانه ها در خرداد ماه برداشت و جهت سیلو نمودن به قطعات 4-2 سانتی متری خرد گردید. سپس با استفاده از مولتی آنزیم ( صفر، 3 و 6 گرم به ازای هر کیلوگرم ماده خشک)، اوره (صفر، 5 و 10 درصد به ازا...
